Presence of microplastics in six bivalve species (Mollusca, Bivalvia) commercially exploited at the Pacific coast of Costa Rica, Central America
(2022-08)
Microplastic pollution represents a serious threat to coastal marine systems. We evaluated the presence of microplastics (MPs) in 168 specimens of six commercially exploited bivalve species in the Golfo de Nicoya, Costa ...
Relaciones hídricas en árboles del bosque tropical seco: el caso de Enterolobium cyclocarpum
(2011)
Las relaciones hídricas en árboles de Enterolobium cyclocarpum del Parque Nacional Santa Rosa, Costa Rica,
se estudiaron en diferentes momentos del curso diurno y a lo largo de dos ciclos fenológicos. La característica ...
C1 compounds shape the microbial community of an abandoned century-old oil exploration well
(2020)
The search for microorganisms that degrade hydrocarbons is highly relevant because it enables the bioremediation of these substances cheaply and without dangerous by-products. In this work, we studied the microbial communities ...
Richness of cultivable endophytic fungi along an altitudinal gradient in wet forests of Costa Rica
(2016-04)
We collected various plant species along an altitudinal gradient ranging from 400 to 2900 m in tropical wet forests of Costa Rica, isolated the associated endophytic fungi, and performed bioinformatic analyses to determine ...
Microplastic ingestion by a herring Opisthonema sp. in the Pacific coast of Costa Rica
(2020-07)
Current knowledge of the presence of microplastics (MP) in marine species in tropical areas is still limited. The presence of MP was examined in the gastrointestinal content of 30 filter feeders of the herring Opisthonema ...
Resistencia a desinfectantes y su relación con la resistencia a los antibióticos
Resistance to disinfectants and their relationship with antibiotic resistance
(2020)
Objetivo: sistematizar los principales mecanismos de acción de los desinfectantes y describir mecanismos de resistencia comunes entre biocidas y antibióticos. Métodos: se realizó una revisión bibliográfica de artículos ...
Dry-season leaf flushing of Enterolobium cyclocarpum (ear-pod tree): above- and belowground phenology and water relations
(2007-11)
Above- and belowground phenology and water relations of Enterolobium cyclocarpum Jacq. trees in the dry
forest of Santa Rosa National Park, Costa Rica were studied during two consecutive phenological cycles, from November ...
Temperature and elemental sulfur shape microbial communities in two extremely acidic aquatic volcanic environments
(2021)
Aquatic environments of volcanic origin provide an exceptional opportunity to study the adaptations of microbial communities to early planet life conditions such as high temperatures, high metal concentrations, and low pH. ...
Fungal Communities in Sediments Along a Depth Gradient in the Eastern Tropical Pacific
(2020-11-06)
Deep waters represent the largest biome on Earth and the largest ecosystem of Costa Rica. Fungi play a fundamental role in global biogeochemical cycling in marine sediments, yet, they remain little explored. We studied ...
Microplastics in feed cause sublethal changes in the intestinal microbiota and a non-specific immune response indicator of the freshwater crayfish Procambarus clarkii (Decapoda: Cambaridae)
(2023-07-18)
Microplastics (MP) are a hazardous pollutant of global concern that threatens aquatic ecosystems and public health. We used the invasive, cosmopolitan, and environmentally versatile red swamp crayfish Procambarus clarkii ...
